Specification forming'part of Letters Patent No. l 55,8 l0, datedOctober 13, 1874; application led February 1c, 1874.Y

To all whom it may concern:

`. Avesters which are made with an inclined lateral extension of.thefplatforim up which the grain is carriedand delivered to the handsof a. riding binder.

In the accompanying drawing, which Vforms a part-of this specification,Figure l is a plan viewof the harvester'tted with my improvement. Fig. 2is a front view of the same. Fig. 3 is a View of one of the rakesisolated from the other parts, showing the means of attachment to thecarrier-chain. Fig. 4 is a side view of said attachment. Fig. 5 isasection across the carrier-chain and adjacent parts. Fig. 6 is an endelevation of my machine, showing portions broken away to displayinterior construction. Fig. 7 is an elevation of the chain-guideroller-frame.

Like letters of reference in all the figures designate like parts.

In the said drawings, A A is the platform, consisting of the horizontalportion Aand the inclined portion A. B is the sickle, and O thereceptacle for the grain at the binders hand. In` a suitable inclosedframe-work, D, lat the back of the platform are mounted the pulleys orrag-wheels E Ef, over which passes the endless chain F, encountering theguide-rollers e at the bend or turn from the horizontal to the inclineof the platform, and also the pressure-rollers e', mounted in aspring-frame, j', which latter, bearing upon the chain, serves to keepit at the proper tension, and allow the rake-connections to pass underthem between them and the chain. The frame-Work D consists of aninclosure or box, the face of which is cut by a continuous groove, d,opposite the chain, throughout its length. Upon the edges of this grooverun the train-wheels t' of the small carriage G, to which is hinged theend of the rake H. A ange upon the wheels i prevents them from escapingfrom the groove.

The course of the chain is indicated by the ar-l rows. The carriage G,to which is hinged the rake, is made curved at one side to allow it topass around the guard-rim J at the lower pulley or rag wheel E. Theupper portion of the groovercl has affixed to the plate D', between thetwo portions (upper and lower) of the said groove, a cam, K, of altrough shape, (shown in section at Fig. 5,) extending from one to theother Aof the rag-wheels E E, and having each end lrounded off, so as totake gradually under the end of the rake, and raise it as it passes backalong the upper groove, so that it may loe out of the way of the reel,which is not shown. The carriage G, to which the rake is pivoted by thearms l and pivot j, is broad enough' to bear upon the case D D at eachside of the groove, being wholly outside of said case, while the wheelsi run within the groove itself, and their anges set against the innerface, `thus holding the carriage in place. The rakes M M consist simplyof a single bar, m, hinged, as stated, to the carriage, and furnishedwith the teeth n. There may be any number of these rakes desired, buttwo will ordinarily be sufficient. The rake M, which is shown traversingthe platform, lies horizontal, with the teeth down, while the rake M,which is upon the upper ply of the chain, and consequently on its returntrip, is elevated nearly to the perpendicular, with its teeth upward.Just 4above the grain-receptacle C is placed a comb, l?, which clearsthe rakes of all grain as they pass. The grain, falling upon thehorizontal portion-0f the platform, is swept up the incline and into thereceptacle C. The rake, having performed this duty, returns by way ofthe upper portion of the groove, and repeats it.

I am well aware that rakes have been heretofore carried backward andfor-ward across a platform by means of an endless chain; and I thereforedo not claim such, broadly.

The spring-frame f is made with a curve corresponding to the curve ofthe frame D, and in it are journaled two guide-wheels, e e', beneathwhich the chain F passes. Two guidewheels are employed to relieve thecurve of the chain of that abruptness which it would have if it passedonly one, and therefore the carriage G will pass the curve at that pointmore easily and with less liability to derangement than would otherwisebe the case. At each end of the carriage f there is a guide-pin, f', anda tension-sprin g, so that it is kept properly down to its work withoutany jarring or tendency to displacement; .and therollers may beperfectly adjusted to equal pressure upon the chain F. The tongue I ispivoted at its rear end to the main frame at or near the main axle, andit is restrained from lateral motion by passing betweenftwo lugs orstandards, t t, located on the front edge of the main frame. The driversseat U is mounted upon the tongue T by means of' the leg u, so that theweight of the driver is supported by the main wheel at one end of thetongue, and by the yoke at the necks of the horses. An elbow-lever, V,pivoted at its elbow to the main frame, extends upward to a pointconveniently within reach of the drivers hand. Its lower or short endextends forward by the side of the tongue, to which it is jointed bymeansl of a pin, through a slot in said lever. With the seat and leverso arranged, the driver can, with ease, change the position of the frontedge of the main frame without said change being influenced by theweight of the driver. The binders foot-board W is hinged at its inneredge to brackets fw, so that it may be turned up or folded out of theway while the machine is being transported from place to place. Itsouter edge is supported by folding braces p. The binders tables' Y arehinged to rods y y, so that they may, whenrfolded down by the side ofthe frame, be slipped endwise, and be' entirely protected against thesaid frame. The outer edges of the binders tables Y are supported byhook-braces z when 1n use.

Having thus fully described my invention, that which I consider new, anddesire to claim as my invention, is-

1. In combination with the horizontal and inclined platform A Al and thegrooved casing standing at the back, provided with the cam-guide K, theendless chain Il, passing over rag-wheels E E', the guide-rollers e e',set in a single frame, f, and the rake-carriage Gr, substantially'as setforth.

2. The spring-framef, with pins f and tension-springs at each end, andprovided with two guide-rollers,combined with the endless chain F andrake-carriage Gr.

3. The guide-cam K, combined with grooved frame D, and carriage Gr, andrake m, `jointed thereto, as set forth. Y

l .4. The 'carriage Gr, having the rake-arm hinged, and provided withflanged wheels t', in combination with the upper and lower edge of saidcam-groove d, as set forth.

5. The binders table Y, hinged to and sliding upon the rod y, andVsupported by the hook-bracez, as and for the purpose set forth.

6. In combination with an endless delivery apparatus and a receptacle,C, to. receive the cut grain, the binders foot-board W, hinged to themain frame, and supported by the jointed braces p, and the tables Y Y,sliding upon the hinge-rod y and supported by the hook-bracez, all inthe manner set forth.
